### Does syntax highlighting work during incremental history search?
Yes!
Highlighting the command line during an incremental history search (by default bound to
to <kbd>Ctrl+R</kbd> in zsh's emacs keymap) requires zsh 5.4 or newer.
If you're using `history-incremental-search-backward` (by default bound to <kbd>Ctrl+R</kbd>
in zsh's emacs keymap) then it works with _zsh version 5.3 and newer_.
If you're using `history-incremental-pattern-search-backward`, then syntax highlighting works
in _zsh 5.3.2 and newer_ due to [a bug in zsh](http://www.zsh.org/cgi-bin/mla/redirect?WORKERNUMBER=40285).
Under zsh 5.2 and older, the zsh-default [underlining][zshzle-Character-Highlighting]
Under zsh versions older than 5.4, the zsh-default [underlining][zshzle-Character-Highlighting]
of the matched portion of the buffer remains available, but zsh-syntax-highlighting's
additional highlighting is unavailable. (Those versions of zsh do not provide
enough information to allow computing the highlighting correctly.)
See [issue #288][i288] for details.
